New K'NEX Ball Machine Element - Cooperating Arms (5-ball)

IMG_3254.JPEG

Hey everyone! I have finally finished my brand new 5-Ball element. I have been working on this for the last couple months and finally have the time to share it with you all. The machine measures about 4 x 4.5 x 7.5 (in blue rods). The machine needs an input of two balls to function. Thereby it outputs two balls, as they cycle through the machine.

If there is any problems, questions, suggestions ect. Let me know! I would love to help you out! :)

I hope you all like it!

Important! The purple connector should be in the exact same orientation as shown on the picture. There are two ways the 2 purple connectors can be clicked together, but in this case there is only one correct way. Otherwise the mechanism will not work properly I think. TIP: look at end of the white rods, and what parts are visible and what part isnt inside of the purple connector.

Use dark blue 3D connectors here, I used the wrong color.

You don't have to ofcourse if you dont care about that sort of thing :p

I dont have a clear picture of where to put the parts on the machine, but it will become more clear soon

The last picture kinda shows how to put the pieces together

I also dont have a picture of where to put it on the machine, oops ':D

The Lift Arm

IMG_3089.JPEG
IMG_3090.JPEG
IMG_3092.JPEG
IMG_3093.JPEG

The position of the yellow rods is really important!

Connect the arm to the trapdoor via the blue rod!

A Doorframe

Having fun so far? Let me know in the comments below :)

Notice the black Y-connectors at the bottom of the path!

An Arch

IMG_3119.JPEG
IMG_3120.JPEG
IMG_3122.JPEG

Notice it doesnt connect with green rods, it just sits on top of the yellow connectors

Also, don't forget the black Y-connector, there is just one of them, this is an important piece

Finishing Touch

IMG_3123.JPEG
IMG_3124.JPEG

Important!!!

IMG_3130.JPG

Try out the trapdoor/push arm mechanism now, if there are any problems, its easier to fix them now! It requires two balls to work! If it doesnt work, try to reduce as much friction as you can, or else look back to see what went wrong.

The Pusher

IMG_3153.JPEG

Connect it to the wall you just made, as shown in the final picture

This part is finally finished now, add it to the machine! :)

Be sure to double check if every single rod is connected!

Connect the pusher to the counterweight with the blue rod!

Another Middle Wall

IMG_3170.JPEG
IMG_3171.JPEG
IMG_3172.JPEG

Be sure you dont miss anything!

The orange connectors at the top mights seem odd (first picture). Its just a regular 2-way orange connector, with two "clips with angled end 3D" into the side of it. One at the bottom and one at the top!

Positive Stop for Arm

IMG_3173.JPEG
IMG_3175.JPEG

I only used the red piece on the left for the red color :)

Connect the arm to the rotating bridge at, using the red rod (as shown in the final picture)

The Upper Arm

IMG_3187.JPEG

Connect this arm to the lower arm with the blue rod (as shown in the final picture)

Ps:

R.I.P. fingers...

Im sorry :p

This Little Thing

No name for this one

A Giant Wall and a Path

Make sure to connect every single rod, especially on the inside of the machine. The ones from the liftarm n such.

I know its a pain to connect this one, but I didnt know how to do it otherwise.

Also, be sure to connect the little path to the main machine.

Transition Path

IMG_3202.JPEG
IMG_3203.JPEG

It doesnt connect at the end, only at the front!

Finishing Touch

IMG_3204.JPEG
IMG_3206.JPEG

The blue connector in the top left will be chaned to a red connector later on. To prevent any confusion :)

Some Extra's

The red connector is visible in the second picture (look back at the previous step if you are confused :)

How many wall does this thing have!?

The blue spacer is important here!

IMG_3224.JPEG
IMG_3225.JPEG
IMG_3227.JPEG
IMG_3230.JPEG
IMG_3231.JPEG

A note about the red part in the second picture:

This ensures a smooth transition, but I noticed the balls are too quick sometimes. If this happens, remove this piece entirely!

IMG_3233.JPEG

The Lever

Note, the two blue rods can be changed out for a red rod. I chose an orange one, but thats purely for aesthetics.

IMG_3252.JPEG
IMG_3253.JPEG

Try to reduce as much friction as you can with this part.

DONE!

IMG_3254.JPEG

The machine uses 5 balls, put 4 balls on the machine as shown in this picture. Put the final one on the top orange lever, and watch your machine go!

Notice: the machine outputs two balls and requires an input of two balls to function

Thats about it! Thanks for building and have a great time with your new element <3
